86 D.J. Stobbelaar et al. Agriculture, Ecosystems and Environment 77 2000 79–93 Fig. 6. Flower rich meadow at farm ‘1’. This meadow is part of the ecological infrastructure of farm ‘1’. Now two families live from the farm and also a next generation coming up may live from the farm. The farm has some rocky outcrops and flowers rich meadows Fig. 6 that serve as part of an ecological in- frastructure Vereijken et al., 1995. Other more natu- ral parts are meadows on the steeper parts, the cliff and the rows of trees planted through the olive groves. One of the rows of Cypresses is a former boundary of the farm, which says something about the admin- istrative history of the farm, but has no real connec- tion with the natural underground, so it does not show vertical landscape coherence. The scattered planting of a few fruit trees between the olive yards did not re- sult in a distinctive landscape element that reflects the natural or cultural history see Kuiper, 2000. 2.5.2. Farm ‘2’ Farm ‘2’ has 11 ha of land. It is scattered through the area Fig. 1. The research group has visited two parcels of this farm, one situated in the hills with high stem olive trees Fig. 4, from now on called plot II, one situated in the planes, with low stem trees Fig. 5, from now on called plot III. Plot II consists of only one landscape element, namely the grove with herbs in the undergrowth. Plot III consists of the grove, a ditch and a surrounding row of native fruit trees and shrubs. The natural grasses and herbs in the under- growth were already mown when we visited the plot. They were not so colourful as the herbs in the moun- tains, probably owing to a much more fertile soil in the floodplain. The herbs and trees were introduced by the organic farmers in accordance the ecological in- frastructure management method Kabourakis, 1996. They can function as ecological reservoirs for preda- tors, to preserve the soil and to improve the ecological quality of the area.

3.1. The quality of the abiotic environment In Table 1 an overview is given of the scores on the abiotic realm of the three plots. On all three plots the ecological olive production system Kabourakis, 1996 is being used. As described in Section 2.1, the agricultural landscape of Crete has become more and more monotonous over the past decades. The ecologi- cal olive production system tries to stop this trend. Although, the environmental situation of plot II and III is a little better than on plot I, this is not elaborated in the ecology of the farm. This might be a management effect, but is certainly a result of the larger surface reserved for semi-natural elements on plot I. 3.2. The quality of the social environment The hill plot and valley plot are part of one economic unit, and because of that treated together here. 3.2.1. Economic factors The organic farmers on the island may make good profit from their work. The number of farmers mem- bers of organic farmers of Messara — is increasing, as a sign that conventional production faces increas- ing agronomic problems while organic olive produc- tion pays off. However, this is mainly due to the suc- cess of the EOPS project initially at agronomic level, and later at management and economic level. Other important factors are the increasing problems of con- ventional production, and the increased awareness of the farmers of the effect of conventional farming on health and environment. The productivity of the organic farmers kilogram’s per hectare is almost as high as conventional, which means that the gross revenue per hectare counted in Drachmas is higher. Besides, the premium prices of olive oil overwrite the extra costs rising from addi- D.J. Stobbelaar et al.

Both farms are not heavily depending on external inputs. Farmers are purchasing the required manure for fertilisation from the area. Legumes in the un- dergrowth provide the most required nitrogen. Some- times, seeds for the cover crops are bought. The main external input to the agro-ecosystem is traps for the olive fly protection. There is limited direct marketing. This is due to the lack of organisation and experience by the farmers. Things would be worse if it was horticulture or staple food instead of a highly appreciated additive to food, like oil. 88 D.J.

On the other hand, only the end product oil is transported, which is less than 10 of the olive’s weight. Olive oil is, in general, a speciality of the Mediter- ranean area. However, Cretan olive oil is of high qual- ity 90 of the olive oil produced in Crete has the highest quality: extra virgin. Next to this, olive oil of the area has specific organoleptic characteristics, e.g. aroma and taste. Cretan olive oil characteristics are since antiquity appreciated by consumers all over the world. Olive oil produced by organic farmers of Mes- sara is appreciated abroad as a speciality product of the area. 3.2.2. Social factors Organic farming provides more types of work, be- cause of a more diversified farming system. This work, although it often is more and heavier work, could sup- ply more satisfaction to the farmer and in that way could contribute to keeping the land populated. Per- haps even more important is the fact that more labour per hectare is needed in organic agriculture. This also might keep the land populated. Note that ecological olive production does overall not require more labour inputs than the conventional intensive olive produc- tion Vassiliou, 1999. The large farm I is special in this respect. The farm is owned by an extended family, instead of a small household. The farm will not be split up by partible inheritance. This gives a solid base for sustainable land use in the sense of long lasting management by providing the possibilities space to make a real effort for ecological network- ing. This on its turn is an important basis for labour satisfaction. There is no direct link to consumers that would like to participate either financially or physically to main- tain the farms. This is to a large extend due to the fact that the group has recently been established dur- ing 1994, and partly due to the fact that there is no tradition, as there is in the Northern European coun- tries with e.g. ‘community based agriculture’. There happen to be some excursions for farmers and re- tailers to the farms, but there are no public roads through the farms, nor ecotourism, self-picking, etc.; there is no real direct contact of visitors with the land, which can establish an emotional bond with the place. As can be seen in Table 2, both farms do contribute to the quality of the social environment rather well, which is largely due to the fact that they are organic farms: they provide labour, do more inspiring work, they are better organised, accessible for visits, and the D.J.

The large farm is more progressive in the way it is socially organised, run by an extended family as a whole and not divided among the hears. 3.3. The quality of the cultural environment Although the plots differ a lot in appearance rela- tively, all three of them score rather well on the cul- 90 D.J. Stobbelaar et al. Agriculture, Ecosystems and Environment 77 2000 79–93 tural parameters Table 3. This is partly related to the fact that the plots are situated in different parts of the landscape. Their landscape appearance is subsequently also different. Nevertheless, plot III lacks behind in the scoring because of its abrupt changes in the land- scape history and the weak reflection of the potential landscape diversity. In contrast, plot I has the highest score because of a high landscape diversity on several levels.
